3 Configuration
3.1 Baud rate
Following baud rates are supported: 2400 baud, 4800 baud, 9600 baud, 19200 baud, 38400 baud,
57600 baud, 115200 baud. The baud rate of the K6 Bt has to match the baud rate of the connected
GPS device. The baud rate of the K6 Bt can be configured in the following way:
3.1.1 Automatic baud rate identification
If no jumper is setted, the K6 Bt tries automatically to detect the baud rate of the connected device.
Detection of the baud rate is only possible when the connected device sends NMEA-0183
conforming data with at least one sentence per second. After the power-on the K6 Bt searches for
the correct baud rate indicated by double blinking of the red LED. If the correct baud rate is found,
the LED stays off. The set baud rate is maintained until the K6 Bt is switched off.
3.1.2 Constant baud rate
The baud rate can be fixed by setting jumpers (see image 4). Using a constant baud rate, the red
LED remains off. The following table shows the configuration variants. Common baud rates can be
realized with a single jumper or a switch. This way the baud rate can be switched in a fast way.
To change the baud rate configuration the K6 bt has to be switched off.
